乐生活Today is May 17. With the development of society and the progress of civilization, more and more countries and regions begin to recognize homosexual love and legalize it. In fact, homosexual behavior is not unique to humans, whether in birds, mammals and other higher vertebrates, or in the majority of arthropods represented by insects, homosexual behavior is widespread.
German animal behaviorist Vitos Drucher once said: "Animal mating instinct and reproductive instinct (sexual impulse) are often separated."
Less than half of the nearly 10,000 known living birds have been documented for reproductive behavior, and more than 130 of them have been observed for homosexual behavior, such as today’s leading black swan.
Cygnus atratus is a large waterfowl that breeds mainly in southeastern and southwestern Australia. It was once classified as a single species: Chenopis. They have bright red beaks, gray-black jio, black feathers floating in green water when the years are quiet, but once the wings are agitated to fly, it can be found that the black swans have a row of white feathers.
There are not only lone swans, but also groups of swans (from hundreds to thousands). The adult black swan is about 1.1-1.4 m in length, with an average weight of 6-9 kg. Males are slightly larger than females, and their beaks are straighter and longer. When flying, the wingspan can reach 1.6-2 M. The neck is slender, the longest of the six swans, usually bent elegantly in the S-shape.
According to statistics, about one-fifth of male black swans choose to love each other through a series of dog abuse behaviors, such as combing feathers, feeding, snuggling together to rest, and raising offspring together. Wait for "Raising offspring?" Yes, you’re right, but it’s not a boy. The first strategy they adopted was to chase off the couple’s black swans and seize their nests and eggs. The second strategy is to "cheat marriage with slag". The combination of husband and black swan will be more competitive and can occupy a larger territory. Once a female black swan is attracted. One of the males will mate with the females and lay eggs, and once the spawning is over, the husband’s black swan will turn its face and refuse to recognize the goose and drive away the poor females, and the husband will work together to raise the offspring.
